True atherosclerotic aneurysms of superficial femoral artery (SFA) are rare and often associated with other peripheral or aortic aneurysms. We report the case of a 84-year-old patient presenting a giant degenerative ruptured aneurysm of the superficial femoral artery. The patient underwent successful aneurysm resection and bypass grafting, with a satisfying long-term follow-up and patency of the graft. The patient was also operated one year before, for a ruptured aneurysm of the abdominal aorta. This case report is rare, because we described a case of patient with multiple atherosclerotic aneurysms, who present, for the second time, a life threating ruptured aneurysm. In this report, we see extreme and rapid evolution of SFA Aneurysm before being symptomatic. Degenerative aneurysms of the lower extremity most commonly involve the popliteal artery, while they are rarely detected in the femoral region (Leon et al., 2008). In this region, aneurysms most frequently involve the common femoral artery (CFA), whereas true aneurysms of the superficial femoral artery (SFA) represent only 15% to 25% of femoral arterial aneurysms [1-5]. Degenerative aneurysms of the SFA display peculiar characteristics (in terms of clinical onset, diagnostic timing, and clinical behavior) so that they differ from other peripheral aneurysms. Because the relative rarity of this location, our case report can be useful to participate to increase the number of reported cases, and define the therapeutic approach for this rare location.
